Which one of the following parts of an ovule possesses reserve food?

The nucellus is the central, multicellular tissue of the ovule that surrounds the embryo sac and serves as a nutritive tissue, storing reserve food for the developing embryo. The integument forms the protective seed coat. The funicle is the stalk attaching the ovule to the placenta. The chalaza is the basal region where integuments and nucellus merge. Hence reserve food is stored in the nucellus.
